Most people experience stomach pain and bloating after eating at some point. Consuming certain foods, eating too fast and emotional stress may contribute to these symptoms. In some cases, pain and bloating after eating indicate medical conditions, such as irritable bowel syndrome, food borne illness or ulcerative colitis. If your symptoms are intense or long lasting, seek guidance from your doctor.
Irritable Bowel Syndrome
Irritable bowel syndrome, also known as IBS, "spastic colon," or "nervous stomach," happens when a person's colon muscle contracts more often than it should, according to the Cleveland Clinic. Though the specific cause of IBS remains unknown, people with the disorder commonly experience bloating and stomach pain after eating, since the digestive process tends to trigger symptoms. People with IBS are also more sensitive to gas, thus exhibit harsher physical responses to gas than others. According to the Cleveland Clinic, IBS primarily affects people in their late teens to early 40s and affects more women than men. Additional symptoms may include excessive gas and hard or loose bowel movements. Certain foods may trigger pain and bloating after eating in people with IBS, such as spicy or high-fat foods and carbonated, caffeinated or alcoholic beverages.
Food Borne Illness
When infectious organisms contaminate food due to improper cooking, mishandling of food or storing food in ways that fail to preserve it properly, food borne illness, commonly known as food poisoning, may occur. Eating poisonous plants, such as certain types of mushrooms, may also cause food poisoning. In reaction to the harmful toxins, people often experience stomach pain and bloating, the University of Maryland Medical Center notes. Nausea, diarrhea or vomiting may follow. Healthy adults with mild to moderate cases of food poisoning often recover within days, without need for medical treatment. Elderly people, young children and others with weak immune systems are more likely to develop serious symptoms, such as severe dehydration, and may require hospitalization.
Ulcerative Colitis
Ulcerative colitis is a chronic disease that causes inflammation and ulcers in the lining of the rectum and large intestine. During flare-ups, or times in which symptoms intensify, digesting food may trigger stomach pain and bloating. According to the National Digestive Diseases Information Clearinghouse, roughly half of people with ulcerative colitis experience mild symptoms only, which may include pain and bloating after eating. More severe symptoms include bloody diarrhea, bouts of chronic constipation, unintentional weight loss and reduced physical development. Though stress and certain foods do not cause ulcerative colitis, they may exacerbate or trigger symptoms.
